Application filed February 18, 1922.

To m7] 107mm it 022052/ concern` Be it known that l, LrMoons Grennnn, a British subject, residing at 823 Beaubien Street, in the city; of Montreal, in the Province of Quebec, in the Dominion of Canada.r` have invented certain new and useful linproveinents in Molds; and l do hereby declare that the following is a true, clear, and exact description of the saine.

The present invention relates to improvements in concrete molds, and is fully described in the following description and illustrated in the accompanying drawings, in which Figure 1 is a plan elevation of a portion of one of the sides of a mold according to the invention.

Figure 2 is a vertical sectional view on line 2/2 of Figure 1.

Figure 3 is a. plan elevation view of the outer surface of one of the mold elements.

Figure 4c is a cross sectional view on line 3/3 of Figure 3.

Figure 5 is a side elevation of one of the mold elements illustrating` the reinforced outer surface.

Figure 6 is a plan elevation of a portion of a modified form of the invention.

Figure 7 is a cross section view on line 7/7 of Figure 6.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings 1 indicates a portion of the vertical walls of a mold consisting of a plurality of narrow sections or members 2, said sections being of elongated narrow construction with fiat inner surfaces 3, and bevelled edges 41 on their outer surfaces 5, said bevelled edges beginning at a suitable distance from the upper end of said members and extending down to its lower edge, and thus is provided a. draining slot and a free space between. each pair of sections behind the joint therebetween, in order to facilitate the cleaning of each of said men'lbers 2. [it the lower end of each of said members 2 the edges are cut out at 6 to provide a wide open space 7 between each pair of members 2, so that the water in the block when squeezed will naturally drip through said open spaces 7. At each end. of said members 2 is provided a hole 8, and 9 a frame also Serial No. 537,525.

provided with holes 10 corresponding with said holes 8 in said members 2, through which the screws 11 project and thread into said holes S, thereby firmly securingl each of said members 2 to said frame 9. Y

ln Figure 5 of the drawings, is illustrated a slightly mod itied forni of the invention in which the member 2 is provided on its outer surface with a reinforcing longitudinal central rib 12.

Without departing from the spirit of the invention, the walls of the mold could be of one piece, as disclosed in Figures G and 7, which consists in providing the side walls of an integral plate 13 having a plurality of draining slots 14, each of said slots having bevelled edges 15, and cut-out portions 16 similar to the bevelled edges and cutout portions G.

rlfhe present invention is an improvement on my United States Fate/nt No. 1,136,225 dated April 20th, 1915.

The object of the present invention is similar to my former patent, but the specific construction of the sections or members 2 has been improved, and it is this particular construction which l am claiming in the accompanying claims.

llVhat l claim as my` invention is 1. A concrete mold, in combination with side walls, comprising a plurality of sections suitably secured to provide narrow draining slots therebetween, each of said menibers having a flat inner surface and bevelled edges on each outer surface; and cut out edge portions at their lower ends, substantially as described.

2. A concrete mold, in combination with side walls, comprising a plurality of sections suitably secured to provide narrow draining slots therebetween, each of said members having a flat inner surface and bevelled edges on each outer surface; cut out edge portions adjacent their lower ends; and means to reinforce said members, substantially as described.

3. A concrete mold, in combination with side walls, comprising a plurality of sections suitably secured to provide narrow draining slots therebetween, each of said members having a flat inner surface and bevelled edges on each outer surface; cut out edge portions adjacent their lower ends;

and a reinforcing longitudinal rib on its adjacent the lower edges of said slots, suhouter surface, substantially as described. stantially as described. 10 4. ln combination with a concrete mold; Signed at lvontreal, Quebec7 Canada, this a side Wall consisting of aplate having a 20th day of January', 1922. y
